Thanks. So I'm a bit confused about what's mounted where but it
appears /usr/local isn't shared?

root_at_master:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 7.9G 2.8G 4.8G 37% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 3.7G 8.0K 3.7G 1% /dev
tmpfs 752M 196K 752M 1% /run
none 5.0M 0 5.0M 0% /run/lock

none 100M 0 100M 0% /run/user
/dev/xvdaa 414G 199M 393G 1% /mnt
root_at_master:~# touch /usr/local/testfile
root_at_master:~# ls /usr/local/
bin etc games include lib man sbin share src test file <-
here's my test file
root_at_master:~# ssh node001
 root_at_node001:~# ls /usr/local
bin etc games include lib man sbin share src <- test file is missing!
